Answer:
Correct Answer: A
Solution:
[a] I. $ CH_3CH=CH_2+H_2O\xrightarrow{{H^{+}}}CH_3\overset{OH}{\mathop{\overset{|}{\mathop{C}}}}HCH_3 $ II. $ CH_3CHO\xrightarrow[(ii)H_2O]{(i)CH_3MgI}CH_3+\overset{OH}{\mathop{\overset{|}{\mathop{C}}}}HCH_3 $ III. $ CH_2O\xrightarrow[(ii)H_2O]{(i)C_2H_5MgI}C_2H_5CH_2OH $ IV. $ CH_2CH=CH_2\xrightarrow[neutral]{KMnO_4}CH_3\underset{OH}{\mathop{\underset{|}{\mathop{C}}}}H\underset{OH}{\mathop{\underset{|}{\mathop{C}}}}H_2 $
